Visit scheduled during the 2009 Mackinac Island Lilac Festival

I've booked my flight in anticipation of my 2009 visit to Mackinac Island. This will be my first visit during the month of June, so I'm looking forward to attending the Lilac Festival.
This visit will primarily focus on research of island history and it's residents. My itinerary is still in development, but I will be on the island June 12-16 and have allowed two days for videotaping and the remaining days for research and a bit of relaxation.
